The Illuminating Engineering Society (IES) recommends a minimum lighting level of 300 lux for classrooms, with higher levels recommended for specific tasks such as reading, writing, and detailed work. However, lighting levels may vary depending on the age and visual needs of the students, as well as the overall brightness of the space.

The color temperature of the lighting can affect mood, behavior, and visual comfort. A color temperature of 5000K to 6500K is typically recommended for the classroom environment, as it provides a bright, cool light that can help to promote alertness and focus.  During the rest period, the color temperature of 3000K to 4000K and with a lower brightness can be set to provide a more relaxing environment.

Glare can cause discomfort and visual fatigue for students, and should be minimized through proper lighting design. This may involve using fixtures with shielding or diffusers to reduce direct glare, and positioning light sources to minimize reflections on whiteboards and other surfaces.

Rapid changes in light intensity, or flicker, can cause eye strain and headaches. Only high-quality and flicker-free LED fixtures should be selected.

Effective lighting design is critical to achieving adequate illumination and visual health in a classroom environment. This may involve a combination of ambient lighting, task lighting, and accent lighting to provide the appropriate levels of brightness and visual comfort for different activities. For example, task lighting may be used for reading and writing, while ambient lighting may be used for lectures and presentations.
